Application filed September 18, 1911. Serial No. 649,943.

To all whom it may concern:

Be it known that I, GEORGE H. Hon- LACHER, a citizen'of the UnitedStates, residing at Portland, in the county of Multnomah and State ofOregon, have invented certain new and useful Improvements in Nozzles, ofwhich the following is a specification.

The present invention relates to an im provement in nozzles and has forits object to provide a nozzle for vacuum cleaners and forsimilarpurposes, having an adjustable means mounted in its lower facefor making frictional contact with the surfaces over which the nozzle ismoved.

A further object is to provide a means of compressing the air' drawninto "the nozzle, into a thin sheet-like stream, thereby increasing itspower of suction, and yet afbottom plan view.

fording space for the removal of particles gathered by the nozzle.

One embodiment of the invention is illustrated in the accompanyingdrawing, in which Figure 1 is an end elevation showing the handlesocket. longitudinal sectional view.

of the nozzle Fig. 2 is a Fig. is 21 Referring to the drawing in detail,2 represents the oblong casing of the nozzle, having the dependingflange 2 and the upwardly inclined tubular extension or socket 6, towhich an operating handle may be applied, and which communicates throughthe opening 7 with the interior of the nozzle. Near each end of thecasing, at the inner side is formed a depending stud 4 provided withscrew threads, and having at its base a shoulder 4. An interior casing3, having the depending flange 3 is made to fit within the outer casing,upon the said studs, and when placed upon the shoulders 4; thereof thelower edge will stand flush with that of the outer casing, therebyleaving a narrow space 8 between the two casings which will have theeffect of concentrating the current through the nozzle, and which willreceive dust and all small particles, except those which should beotherwise removed. The inner casing will be held in place upon the studsby means of nuts 5. Below the inner casing, upon each of said studs, isplaced a nut 9 against which the plate 11 carrying the teeth 12 rests.This plate is held in place by the nuts 10, bearing against its lowerside. By adjustment of these nuts the plate may be raised and lowered soas to vary the position of the teeth with reference to the edges of thecasings. The tips of the teeth should be adjusted to bear slightly uponthe surface of the article being cleaned, though they may be lowered sothat most of the weight will rest upon them, in caseswhere vigorousagitation is necessary to dislodge the dust collected in the article. Onthe other hand the teeth may be raised so as to stand entirely above thearticle, in cases where injury might be caused. v

By the use of the device herein shown it is possible to remove dust fromdelicate fabrics without injury; and coarser articles may be agitated toany degree desired ac cording to their condition and texture.

Having now described my invention so that others skilled in the art towhich it. pertains, may make and use the same, what I claim is- 1. As anew article of manufacture. a base having a depending annular flange. atubular stem opening within the flange and rising from the upper surfaceto form a hand hold, studs secured upon the lower face of said base, acontact plate having rigid teeth on its outer surface secured upon saidstuds, and means for adjusting the plate on said studs, whereby theteeth may be raised and lowered with reference to the edge of saidflange.

2. A nozzle comprising a base having a depending annular flange, atubular stem opening within the flange and rising from the upper surfaceof the base to form a hand hold, studs secured upon the lower face ofsaid base, an inner casing conforiuing in outline to said base andflange secured upon said studs in position to form a narrow spacebetween the two casings cominunicating with said tubular stem, a con- Intestimony whereof afiix my signataet plate having rigid teeth on itsouter ture in presence of two Witnesses. face secured upon said studs,below the GEORGE H HORLACHER' inner casing, and means for adjusting the5 plate on the studs, whereby the teeth may WVit-nesses:
